Question

What is the current if 4 ohm and 3 ohm resistors connected in series and 7 v potential difference?

Answer 1

Hi but what are we do you hdidmbd

Answer 2

Answer:

Current(I)=1 Ampere

Explanation:

Equivalent Resistance (R) = R1+R2

                                                                    =4+3= 7 ohm

Potential Difference (V) = 7 volts

Potential Difference=Current(I) * Resistance

V=IR

7 = I * 7

I = 7/7

I = 1 Ampere

Therefore Current(I) = 1 Ampere

Hope it helps.
