1.	If the EMF of a cell is 1.5 V, then the energy provided by the cell to drive 0.5 C of charge around the circuit : (A) 1 J (B) 0.75 J (C) 0.5 J (D) 0.25 J
Answer» (B) 0.75 J Energy = work done (w) = vq w = 1.5 x 0.5 = 0.75J

If the EMF of a cell is 1.5 V, then the energy provided by the cell to drive 0.5 C of charge around the circuit : (A) 1 J (B) 0.75 J (C) 0.5 J (D) 0.25 J

Answer»

(B) 0.75 J

Energy = work done (w) = vq

w = 1.5 x 0.5

= 0.75J
