Question

the potential difference between two points of a wire is 150mV . the wire has a resistance of 50ohm . find the current flowing through the wire

Answer 1

v=150
r=50
according to question
v=ir
150=i×50
i=150/50
i=3 ampr

Answer 2

Given - Potential difference and resistance

Find - Current

Solution - Potential difference, current and resistance are related to each other as follows-

V = I*R

As per the known fact, 1000 mV = 1 Volt

150 mV = $\frac{1 \times 150}{1000}$

Performing multiplication and division

Potential difference = 0.15 Volts

Keep the values in formula to find the current flowing throught the wire.

I = $\frac{0.15}{50}$

Performing division

I = 0.003 Amp

Hence, the current flowing through the wire is 0.003 Amperes.
