Question

Find out the emf of one cell if 6 electric cells are connected in series in an electronic device which works at 9v potential difference

Answer 1

Answer:

The emf of each cell is 1.5 volts

Explanation:

Given as :

The 6 electric cells are connected in series

The working potential difference = v = 9 volts

let The emf of each cell = x volts

According to question

Since The cells are connected in series

So, For series connection

equivalent voltage = $E_eq$ = $v_1 + v_2 + v_3 + v_4 + v_5 + v_6$

Or, 9 volts = x + x + x + x + x + x

Or, 9 volts = 6 x

or, x = $\dfrac{9}{6}$

Or, x = 1.5 volts

So, The emf of each cell = x = 1.5 volts

Hence, The emf of each cell is 1.5 volts Answer
