How to work out the resistance
Web14 dec. 2024 · What it is. A combined network is any combination of series and parallel circuits wired together. Consider finding the equivalent resistance of the network shown below. We see the resistors R 1 and R 2 are connected in series. So their equivalent resistance (let us denote it by R s) is: R s = R 1 + R 2 = 100 Ω + 300 Ω = 400 Ω.; Next, … Web6 okt. 2016 · Since it is given that total power is 60 watts, and the series circuit has 120v, then we can calculate total resistance to be RT = (120*120)/60 = 240 ohms We know we currently have a total known resistance of R1 + R3 = 180 ohms. So R2 = 240 - 180 = 60 Ohms - Current in the circuit

Rso is the outside surface resistance, and Rsi is the inside surface resistance. These values are specified in the Architects Pocket Book as: Web21 dec. 2024 · The Ohm's law formula can be used to calculate the resistance as the quotient of the voltage and current. It can be written as: R = V/I. Where: R - resistance. V - voltage. I - Current. Resistance is expressed in ohms. Both the unit and the rule are named after Georg Ohm - the physicist and inventor of Ohm's law.
