## Which AC voltage produces the same heating effect as a DC voltage of the same value?

In fact, an effective description of “the RMS voltage” for an AC voltage is that voltages which produces the same heating as the same voltage of DC. In the US, our wall outlets are 120 v RMS. That means if you connected a resistor to an outlet, it would be the same as if you had connected it to 120v DC.

## Which will produce more heat AC or DC?

Infact, for a given time, the AC would generate half the amount of heat compared to DC.

Do electric heaters use AC or DC?

Residential space heaters are designed to run on AC power. In North America, that means they run on 120V AC. In most cases, the electrical system in a car provides 12V DC, which can fluctuate up or down depending on factors like the battery charge level and the overall load on the system.

What is the formula for electric heat?

Hence the heating effect produced by an electric current, I through a conductor of resistance, R for a time, t is given by H = I2Rt. This equation is called the Joule’s equation of electrical heating.

### What is the term called if the same heating effect produced by DC on that of an AC?

The term “RMS” stands for “Root-Mean-Squared”. Most books define this as the “amount of AC power that produces the same heating effect as an equivalent DC power”, or something similar along these lines, but an RMS value is more than just that. The symbols used for defining an RMS value are VRMS or IRMS.

### Why do we use RMS?

Attempts to find an average value of AC would directly provide you the answer zero… Hence, RMS values are used. They help to find the effective value of AC (voltage or current). This RMS is a mathematical quantity (used in many math fields) used to compare both alternating and direct currents (or voltage).

What is DC and AC voltage?

AC means Alternating Current and DC means Direct Current. AC and DC are also used when referring to voltages and electrical signals which are not currents! An electrical signal is a voltage or current which conveys information, usually it means a voltage. The term can be used for any voltage or current in a circuit.

What is the difference between AC and DC voltage?

In direct current (DC), the electric charge (current) only flows in one direction. Electric charge in alternating current (AC), on the other hand, changes direction periodically. The voltage in AC circuits also periodically reverses because the current changes direction.

#### What is a dc heater?

Heaters can be built to your specification for direct current operation. …

#### What is difference between AC and dc heater?

When inquiring about heating element, most customers would like to specify the power either AC or DC. AC is short of alternating current while DC is that of direct current. In alternating current (AC), the flow of electric charge periodically reverses direction.

How many volts is an electric heater?

Most space heaters are 120 volts, but some wall heaters designed for home use are rated at 240 volts and are just as powerful as garage heaters.

Do electric heaters work on AC or DC?

There are three major kinds of electrical heating used in domestic heater appliances. The resistive heating will work on any supply both ac and dc. Very simple. Just connect the coil and it will work. However, if you go for an induction heater. You need ac, but not just any ac, a very high frequency ac of around 100kHZ.

## How does voltage affect the power of an electric heater?

How Applied Voltage Affects the Power Output of Your Heater Let’s start with the basics: an electric heater is a resistive device; that is, it provides opposition to current flow when a voltage is applied. When it does so, it dissipates power in the form of heat.

## Is it possible to convert AC voltage to DC voltage?

No, provided that the AC voltage is equivalent to the DC voltage. AC (alternating current) voltage is usually represented as its RMS, or “root mean square,” value.

How does an electric heater work?

Let’s start with the basics: an electric heater is a resistive device; that is, it provides opposition to current flow when a voltage is applied. When it does so, it dissipates power in the form of heat. We can calculate how much power a resistive load can handle using the following equation:
