Question

27. If a cell of 9 V sends a
current of 9 mA, then
resistance of the circuit is
1 Ω
Ο 10Ω
Ο 100 Ω
Σ
Ο 1000Ω​

Answer 1

Answer:

1000ohm

Explanation:

we know, v = I x R

or, R= V/I

or, R=9V/9mA

or, R=9000V/9A (since, 1mA=0.001 A)

or, R= 1000ohm

Answer 2

Answer:

R=1000Ω

Explanation:

hope it helpss you
