Explanation / Answer

40.

Since in parallel circuit voltage will be equal in each resistance, So

Current in 40 ohm will be, from ohm's law:

i1 = V/40 = 0.025*V

Current in 20 ohm will be, from ohm's law:

i2 = V/20 = 0.05*V

if we compare both current we can see that for a constant voltage, current will be higher in 20 ohm

Correct option is C.

41.

In Series circuit

Req = 10 + 5 = 15 ohm

Using ohm's law:

V = i*R

i = 12/15 = 0.8 Amp

Now Since it's series circuit, So current in each resistor will be equal to total current

Current in 10 ohm = 0.8 Amp

Voltage in 10 ohm will be

V = i*R

V = 0.8*10 = 8.0 V

Correct option is C.
