Lab10_1 Figure 10.5 An electrical circuit R2 Ohm's Law V-i*R4 I-current in amps V- voltage in volts R resistance in ohms Kirchoff's 2nd Law drops in a circuit V1-voltage source Analysis of the circuit is to determine all the currents and voltages. Solution . Select loop currents in the circuit arbitrarily : Sum of the voltage (loop) must be zero 2. Three loop currents will allow the determination of all the voltages and currents in the circuit
