Answer

Using Kirchhoff's law, the current entering (6.0 A) must equal the sum of the currents leaving (3.5 A + current in wire H).

Thus, we have: $6.0 = 3.5 + I_H$

Solving for $I_H$ gives: $I_H = 6.0 - 3.5 = 2.5 ext{ A}$ .

Step 5

Calculate the quantity of charge that flows through the wire in 50s.

Answer

Using the equation: $ext{charge} = ext{current} imes ext{time}$ ,

Substituting the given values: $Q = 0.9 ext{ A} imes 50 ext{ s}$

This results in: $Q = 45 ext{ C}$ .

The unit of charge is coulomb (C).
