Answer:

Option C

Explanation:

From Ohms law, voltage across circuit is given as rhe product of resistance and current. Therefore, V=IR where I is cureent, R is resistance and V is voltage.

Consjdering the options given, we calculate voltage across each then

V=IR

OPTIONS

A

I=20 A, R=16 Ohms

V=IR=20*16=320V

OPTION B

I=10A, R=10 Ohms

V=10*10=100 V

OPTION C

I=25 A, R=16 Ohms

V=25*16=400 V

Oprion D

I=20 A, R=10 Ohms

V=20*10=200 V

From the calculations, it is option C that yields the highest voltage.
