250 Ohm Resistor. The MeshCurrent Method also known as the Loop Current Method is quite similar to the Branch Current method in that it uses simultaneous equations Kirchhoff’s Voltage Law and Ohm’s Law to determine unknown currents in a network It differs from the Branch Current method in that it does not use Kirchhoff’s Current Law and it is usually able to solve a circuit with less unknown.

The 250 Ω resistor will experience a current of 40 mA while the 800 Ω resistor will experience a current of 125 mA Notes As an instructor I was very surprised to hear many beginning students claim that all current would go through the lesser resistor and none through the greater resistor!.

To find the necessary resistor value we use Ohm’s law this gives us So the necessary value for the current limiting resistor is 200 Ohms Choosing the right resistor So you know that you need a 200 Ohm resistor But when you look for components you find that there are several different types of resistors Well the only thing you need to be aware of is the wattage.

the current through each resistor the voltage drop across each resistor the power dissipated in each resistor solution Follow the rules for series circuits Resistances in series add up R T = R 1 + R 2 + R 3 R T = 20 Ω + 30 Ω + 50 Ω R T = 100 Ω Total current is determined by the voltage of the power supply and the equivalent resistance of the circuit I T = V T /R T I T = 125 V.
