Question

A potential difference of 20V appears across the ends up a resistor when 2.5 A of current is passed through it. What is the resistance of the resistor?​

Answer 1

Answer:

According to Ohm's law , Potential Difference ( V ) applied is directly proportional to current ( I ) rises or decrease in circuit , i.e

▶️ \underline{V\: \alpha\: I }

VαI

=> V = I × R

✔️ \boxed{R\:= \:V / \: I }

R=V/I

⏺️ R is resistance

▶️ Given , V = 10 Volt ; I = 5 A

=> R = V / I

=> R = 10 / 5

=> \boxed{R\:= \:2 \: Ω }

R=2Ω

♠️ So the resistor will be of 2 Ω
