Explanation Formula used: Write the expression for potential difference ( Δ V ) . Δ V = I R Here, I is the current, and R is the resistance. Explanation: Redraw FIGURE P23.33 as shown in Figure 1. Apply Kirchhoff’s voltage law for Loop 1. 12 V − I 1 ( 3.0 Ω ) − ( 4.0 Ω ) ( I 1 − I 2 ) = 0 I 1 ( 3.0 Ω ) + ( 4.0 Ω ) ( I 1 − I 2 ) = 12 V ( 7.0 Ω ) I 1 − ( 4.0 Ω ) I 2 = 12 V (1) Apply Kirchhoff’s voltage law for Loop 2. − ( 48 Ω ) ( I 2 − I 3 ) − ( 4.0 Ω ) ( I 2 − I 1 ) = 0 ( 4.0 Ω ) I 1 − ( 52 Ω ) I 2 + ( 48 Ω ) I 3 = 0 (2) Apply Kirchhoff’s voltage law for Loop 3. − ( 16.0 Ω ) I 3 − ( 48 Ω ) ( I 3 − I 2 ) = 0 − ( 64 Ω ) I 3 + ( 48 Ω ) I 2 = 0 ( 64 Ω ) I 3 = ( 48 Ω ) I 2 I 3 = ( 48 Ω 64 Ω ) I 2 I 3 = ( 0.75 ) I 2 (3) Substitute ( 0.75 ) I 2 for I 3 in equation (2), ( 4.0 Ω ) I 1 − ( 52 Ω ) I 2 + ( 48 Ω ) [ ( 0.75 ) I 2 ] = 0 ( 4.0 Ω ) I 1 − ( 52 Ω ) I 2 + ( 36 Ω ) I 2 = 0 ( 4.0 Ω ) I 1 − ( 16 Ω ) I 2 = 0 ( 16 Ω ) I 2 = ( 4.0 Ω ) I 1 Simplify the equation. I 2 = ( 4.0 Ω ) ( 16 Ω ) I 1 I 2 = ( 0.25 ) I 1 (4) Substitute ( 0.25 ) I 1 for I 2 in equation (1), ( 7.0 Ω ) I 1 − ( 4.0 Ω ) [ ( 0.25 ) I 1 ] = 12 V ( 7.0 Ω ) I 1 − ( 1.0 Ω ) I 1 = 12 V ( 6
