Question

find current and total resistence
find the equal resistancy voltage across 7 resistance resistor
​

Answer 1

Answer:

Let the applied emf be V

1

.

Equivalent resistance of the circuit,

R=7Ω+

(5+10)Ω

(5Ω)(10Ω)

=7+

15

50

=10.33Ω

Total current, I=

R

V

1

=

0.33

V

A

∴ Potential difference across 7Ω resistors.

V
