Please help me If a circuit has a current of 0.25 A and a voltage of 3 V, how much resistance is in the circuit? A 0.083 ohms B 0.75 ohms C 1.5 ohms D 12 ohms

The resistance in the circuit is 12 ohm.

(D) is correct option

Explanation:

Given that,

Current = 0.25 A

Voltage = 3 V

We need to calculate the resistance

Using ohm's law

Where, V = voltage

I = current

R  = resistance

Put the value into the formula

Hence, The resistance in the circuit is 12 ohm.

(D) is correct option

when jerome paddle in flowing river towards east the net speed of jerome will increase

so the net speed of jerome will be given as

now the speed of paul will be same as it is given as he is running on the ground

so

so here we can say since the speed of jerome is more so he will win the race

now as we know the distance so the time difference is given as

so jerome will reach first and the time difference will be 203.55 s or 3.4 min
