Electrical Power & Energy

P = VI = 6 \times 2.00 = 12.0\ W \quad E = Pt = 360\ J

Current2.00 A

Power12.0 W

Energy transferred360 J

Voltage (V)6

Resistance (Ω)3

Time connected (s)30

Set 6 V across 3 Ω and confirm the current is 2 A
With 6 V, 3 Ω and 30 s, confirm the load transfers 360 J
Keep 6 V and 3 Ω, then double the time to 60 s and confirm the energy is 720 J
Set 12 V across 6 Ω and confirm the power is 24 W
