A hundred volt power supply is used to power a twenty ohm resistor, which is joined to a ten ohm resistor and a fifteen ohm resistor in parallel. A parallel combination of a ten ohm resistor and a five ohm resistor is linked(connected) to the fifteen ohm resistor as well. The five ohm resistor is joined/connected to a voltage source of eighty volts. Create a sketch of the thevenin circuit &  use the thevenin theorm approach to determine the currents, voltage drop, and power dissipated in the ten ohm resistor.

Show me how to approach this problem with steps please

Question: The current in the 8.00 ohm resistor below is 0.84 A a.) Find the current in the 20-ohm resistor and in the 9-ohm resistor. b.) Find the equivalent resistance across the circuit.

An eleven volt power supply is used to power a four ohm resistor, which is joined to a one ohm resistor and a seven ohm resistor in parallel. A parallel combination of a two ohm resistor and a three ohm resistor is linked(connected) to the seven ohm resistor as well. The three ohm resistor is joined/connected to a voltage source of thirteen volts. Create a sketch of the Norton equivalent circuit  & use the norton theorm approach to determine the currents, voltage drop, and power dissipated in the two ohm resistor.

What resistance must be connected in series with a 100-N resistor for the 100-0 resistor to produce heat at the rate of 30 W when the combination is connected to a 120-V source?
