questions are in the picture,
help please!?​

Answer 1

Explanation:

1) = given - R = 20 ohms

I = 15 amperes

to find - V ( potential difference l

solution= by formula, V= R× I

= 20×15

= 300volt.

2) given - R = 6 ohms

potential difference = 3 volts

to find - what current (I) is flowing

solution- by formula, V= R × I

3=6×I

I = 6 / 3

I = 2 amperes
