A circuit has three resistors in parallel – its schematic is in Figure 1.- The voltage source labeled Vbat is 12 V. Theresistors are R1 =20 k ohms, R2 =

50 kohms and R3=200 kohms . Determine the equivalent resistance Reg, that could replace the 3 resistors. O Determine the currents in each branch of the circuit: I, I1, I2 and I3. Demonstrate that Kirchoff's current law is true at node A; the total of currents in and out must be zero.
