ΣΙ= 0 E Figure 1 R3 1.0 ΚΩ C Kirchhoff's Voltage Law: The algebraic sum of the potential difference in any closed circuit is equal zero. Σ V = 0 D Procedure: Measure the e.m.f. of V, and V₂ by using d.c voltmeter before connecting the circuit and record the values. V₂ = 3.0 V Connect the circuit as shown in Figure 1. With a d.c. voltmeter, measure the potential difference (p.d.) across all resistors in the circuit. Note the polarity or direction of each potential difference values, Record the readings in Table 1, Table 2 and Table 3. With a d.c. ammeter, measure IAB, ICB and IBE. Note the direction of the current and record the readings in Table 4. Results: e.m.f. and potential difference in loop ABEF: e.m.f. V₁ Σ. e.m.f e.m.f. and potential difference in loop BCDE: e.m.f.
