1.	An electric heater of resistance 230 ohm is connected to 230 volt supply calculate the heat energy produced by it in one second
Answer» 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 #BrainLock.

Answer»

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
