HNC electrical principles
can somebody help me break this down ive managed to draw out the circuit i understand working the Rth for this is simple but im really struggling with Vth as there is two voltage sources
Two DC supplies are connected in parallel, with their positive terminals connected together. The voltage and internal resistance of battery B1, is 120 volts and 10 Ω respectively, and the corresponding values for B2, are 150 volt and 20 Ω. The two connections of the parallel combination are brought out to two terminals, A & B.
a) Draw a circuit diagram of the above arrangement.
b) Calculate and draw the Thevenin equivalent circuit.
c) A 50 Ω resistor is now connected across terminals A & B. Determine the current through the 50 Ω resistor.
d) Calculate the magnitude and direction of flow of the current through each battery.
e) If the 50Ω resistor is changed to 20 Ω, determine the new value of current through it
