Circuit Power (Watt) Measurement

Circuit Power (Watt) Measurement: R = 1 ohm V = 1.5 V Since the load is resistive: I = V / R I = 1.5 / 1 I = 1.5 A Power is: P = V × I So: P = 1.5 × 1.5 P…

How it works

Circuit Power (Watt) Measurement:

R = 1 ohm

V = 1.5 V

Since the load is resistive:

I = V / R

I = 1.5 / 1

I = 1.5 A

Power is:

P = V × I

So:

P = 1.5 × 1.5

P = 2.25 watts
