Question

123. If the EMF of a cell is 1.5 V, then the energy
provided by the cell to drive 0.5C of charge
around the circuit :
((1) 11
(2) 0.75 J
(3) 0,5)
(4) 0.25 )​

Answer 1

Answer:

option (a) 11 is the answer

Answer 2

Given:

E.M.F of a cell = ɛ = 1.5v

Cell drive = q = 0.5C

To Find:

Energy provided by the cell to drive 0.5c of charge around the circuit

Solution:

Applying the formula of energy -

ɛ = W/q

Or W = ɛ x q

Therefore, substituting the values -

W = 1.5 x 0.5

W = 0.75

= 0.75J

Answer: The energy provided by the cell to drive 0.5 c of charge around the circuit is 0.75 J
