Question

2 IS MOT A heater in an electrical circuit has a current of 5 A passing through it and a potentia difference of 240 V across it. What is the power of the heater in cents​

Answer 1

To calculate the power of the heater, we can use the formula:

Power = Current x Voltage

In this case, the current is 5 A and the voltage is 240 V, so we have:

Power = 5 A x 240 V

Power = 1200 watts

Step-by-step explanation:

To convert watts to cents, we need to know the cost of electricity in cents per unit of energy (usually measured in kilowatt-hours, or kWh). For example, if the cost of electricity is 15 cents per kWh, then the cost of running a 1200 watt appliance for one hour would be:

1200 watts = 1.2 kilowatts

1.2 kilowatts x 1 hour = 1.2 kilowatt-hours

1.2 kilowatt-hours x 15 cents/kWh = 18 cents

So the cost of running this heater for one hour would be 18 cents, assuming a cost of 15 cents per kWh.
