Question

the PD between the terminals of an electric heater of 60V when it draws a current of 4A from the source what current will the heater draw if the PD is increased to 120V ​

Answer 1

Answer:

8A

Explanation:

volt is directly proportional to current

60v  = 4a

120 = x

120*4/60

x = 8a

Answer 2

Answer:

Current in the circuit is 8 A

Explanation:

PD = 60 V

I= 4A

A/C to Ohm's law

V = IR

60=(4)R

R=15 ohm

SECOND SITUATION

PD=120 V

R= 15 ohm

I = V/R

I = 8 A
