Question
In the circuit shown below, the magnitude of current (in ampere) that flows from a to b when switch S is closed, is
Open in App
Solution
When S is closed, no current through
5
Ω
resistor because it is short - circuited So, current will pass from b to a and then
10
Ω
the
10
Ω
resistor is directly connected across the cell
From V= IR (ohm's law), the current through
10
Ω
resistor
I
=
10
V
10
Ω
=
1
A
→
this is from b to a.
So current from a to b = -I = - 1 A
Hence magnitude of current from a to b = 1 A.
