This physics video tutorial explains how to solve series and parallel circuits. It explains how to calculate the current in amps through each resistor and the voltage in volts across each resistor with three resistors in series and parallel combination using a few simple formulas including ohm's law. Parallel resistors form a current division circuit and series resistors form a voltage division circuit. This video also explains how to calculate the electric power delivered by the battery in watts and the power absorbed by the resistors.

At 8 minutes im confused as to why in a parallel circuit part of series paralell you have to do the math where v1=v2=VT in series votlage drops but in parallel it doesn't amperage does.

@isaacturner199 Жыл бұрын

This is a very late reply, but that's just a rule that usually gets taught along with Ohm's law. In parallel voltage always stays the same. Technically each parallel line of resistance is still voltage coming straight from the source and meeting resistance for the first time. So the voltage is the same in each instance. In series after each resistor it is hitting is it's 2nd, 3rd, 4th resistor since leaving it's source, so the voltage continues to be reduced. Hope that makes sense.

@engineershexamartin 2 жыл бұрын

Thanks very much. I appreciate your clear explanations and how you make these circuits simple. However, do you mean to say the answer for part (c) is 12Volts passes through 6Ohms resistor and 8Volts passes through 5Ohms resistor and 8Volts passes through 20Ohms resistor?

@@gauche637 they are not all in parallel since the voltage source is sharing the same wire or nodes(nodes being A and B) as the one resistor. So in this case A and B share the same nodes with no other components on those wires so they are in parallel. However if there was another resistor on there bottom wire it would be in series with the 5 ohm and then the sum of the two in parallel with the 20 ohm one.

@willsmith1968 3 жыл бұрын

It's raised because it takes the inverse of the fraction. If 1/Req=1/R1+1/R2+... then you need to raise it to the -1 power to get your Req to the numerator, if that makes sense.

If river can go either way so it means that has less resistance than if can go only one way. If river has only one way it has to go through all resistance, but if river has more paths she will go little here little there 😁.

Thank you for helping me understand this topic? Is it possible for you to explain the conceptual reason behind why you need to add the reciprocals and then find the reciprocal of the sum for resistors in parallel?

@cooldawg2009 2 жыл бұрын

Bc the total Current accross the parallel circuit corresponds to an “equivalent” resistance (which is just basically an avg of the total resistance in the circuit). So taking this and setting up a formula for total Current I(T) we get: I(T) = I(1) + I(2) And since I=V/R, Total Current in parallel circuit is equivalent to the total Volts, V in circuit divided by the equivalent Resistance R(EQ). Our equation now becomes: V/R(EQ) = V/R1 + V/R2 Remember that Volts are same accross each circuit in parallel so dividing the whole equation by V yields: 1/R(EQ) = 1/R1 + 1/R2 Now to solve for R(EQ) we just take the inverse if both sides which yields R(EQ) = 1/(1/R1 + 1/R2) And that’s why you have to take the inverse of the sum of the inverted resistances in a parallel circuit.
