Question

An electric heater of resistance 230 ohm is connected to 230 volt supply calculate the heat energy produced by it in one second

Answer 1

Answer:

Given:

Resistance of the electric heater = 230 ohms = R

• Voltage or the potential difference = 230 volts = V

Time = 1 second = t

To find :

Heat energy produced by the heater in 1 second

Heat energy = Vxlxt

Using ohms law :

V=IxR

230=1x230

$i = \frac{230}{230}$

| = 1 ampere

The current passing through the heater is 1 ampere

Now using the formula:

Heat = 230x1x1

Heat = 230 Joules

The heat energy produced is equal to 230 joules

Note:

this can also be found with the formula 1²RT
