Question

A p.d. of 240 volts is applied across a heating element resistor of 30 ohms.How much current flows through the heater?

Answer 1

Answer:

Current is 8 ampere

Explanation:

Potential difference=240 Volts

Resistance=30 ohm

to find current

formula is I=V/R

I=240/30

I=8 Ampere

Answer 2

Answer:

v =240 v and r =30π so current( I)= ?

we know that,

v=ir

240v= i×30π

240÷30= I

80=I

I= 80A
