1.	An electric device operates at 24V and has a resistance of 8Ω Calculate the power of the device and current flowing through it.
Answer» V = 24V, R = 8Ω (i) P = V²/R = (24 x 24)/8 = 72W (ii) Current flowing P = VI 72 = 24I I = 72/24 = 3A

An electric device operates at 24V and has a resistance of 8Ω Calculate the power of the device and current flowing through it.

Answer»

V = 24V,

R = 8Ω

(i) P = V²/R = (24 x 24)/8 = 72W

(ii) Current flowing P = VI

72 = 24I

I = 72/24 = 3A
