Answer 1

Question :

200 μC charge flows through a conducting wire in 1ms. Find current passes through a wire.

Given :

Charge flow = 200 μC

Time interval = 1ms = 10‾³ s

To Find :

Current flow through conducting wire.

Solution :

❖ Electric current is defined as the rate of charge flow per unit time.

• It is a scalar quantity having only magnitude.
• SI unit : A (ampere)
• Dimension formula : [A¹]

Formula : $\underline{\boxed{\bf{\purple{I=\dfrac{Q}{t}}}}}$

» I denotes electric current

» Q denotes charge flow

» t denotes time

By substituting the given values;

➙ I = Q / t

➙ I = 200 × 10‾⁶ / 10‾³

➙ I = 200 × 10‾³

➙ I = 0.2 A

Answer 2

☆Question☆

200 μC charge flows through a conducting wire in 1 ms. Find current passes through a wire.

☆Answer☆

Given,

Charge flow = 200 μC

Time interval = 1 ms = 10‾³ s

To calculate the amount of current

=> I = Q / t

=> I = 200 × 10‾⁶ / 10‾³

=> I = 200 × 10‾³

=> I = 0.2 A

Hence, the current passing through wire is 0.2 Amp.
