Question

An ammeter placed in series with an electric radiator reads 0.5A
and a voltmeter placed across it reads 230 volts. What is the
resistance of the radiator?

Answer 1

Answer:

V= I R

where,

V is the voltage

I is the current

R is the resistance

SO,

R= V/I

= 230 / 0.5

= 460 ohms

Answer 2

Explanation:

I =. 5 Ampere

V= 230v

V = IR

230 = 0.5 × R

R = 230/0.5

=2300/5

=460 ohm
