(a) At Junction B, the sum of currents entering the junction is equal to the sum of currents leaving the junction.
ΣCurrents in = ΣCurrent out
6 A = 4 A + IR
IR = 2A
Current through resistor R is 2A
In the circuit shown in the figure (Figure 1) find
(a) the current in resistor R
(b) the resistance R
(c) The unknown emf ℰ
(d) If the circuit is broken at point x, what is the current in resistor R?
