Question

Calculate the electrical power when the current is 1.5A and the resistance is 200Ω.

Answer 1

Answer:

P = I² R

P= (1.5)² × 200

P = 450 watt

Answer 2

Answer:

450 watts

Explanation:

Given :

• Current passing through the circuit = I = 1.5 Amperes

• Resistance of the resistor = R = 200 ohms

To find :

• Electrical power when the current is 1.5 Amperes and resistance is 200 ohms

Using ohms law : V=IR

V=1.5×200

V=300 volts

Electrical power = Voltage × current

Electrical power = 300×1.5

Electrical power = 450 watts

The electrical power in the circuit is equal to 450 watts
