Question

A wire in a circuit carries a current of 0.9 A. Calculate the quantity of

Answer 1

Answer:

We conclude that the quantity of  the charge that flows through the wire in 50 s will be 45 C.

Explanation:

Given

• Current I = 0.9 A

• Time t = 50 s

To determine

We need to find the quantity of  the charge that flows through the wire in 50 s.

Important Tip:

A current of 1 Ampere = 1 Coulomb  of charge flowing in 1 second

Using the formula involving charge and current

$I=\frac{Q}{t}$

where:

• $I$ represents the current in amperes (A)

• $Q$ represents the charge in coulomb (C)

• $t$ represents the time in seconds (s)

now substituting I = 0.9 and t = 50 in the formula

$I=\frac{Q}{t}$

$0.9\:=\:\frac{Q}{50}$

switch sides

$\frac{Q}{50}=0.9$

Multiply both sides by 50

$\frac{50Q}{50}=0.9\cdot \:50$

Simplify

$Q=45$ C

Therefore, we conclude that the quantity of  the charge that flows through the wire in 50 s will be 45 C.
