How do you find the resistance in a combination circuit?

If you know the total current and the voltage across the whole circuit, you can find the total resistance using Ohm’s Law: R = V / I. For example, a parallel circuit has a voltage of 9 volts and total current of 3 amps. The total resistance RT = 9 volts / 3 amps = 3 Ω.

Why would it be a problem if your household appliances were connected in a series circuit?

Household appliances aren’t connected in series because if they were they would have to “share” the line voltage with the other appliances in the circuit. Each lamp increases the resistance in the circuit, which decreases the current through the circuit.

What does a combination circuit look like?

A combination circuit is one that has a “combination” of series and parallel paths for the electricity to flow. Its properties are a combination of the two. In this example, the parallel section of the circuit is like a sub-circuit and actually is part of an over-all series circuit.

What should be used to solve the unknown values in a combination circuit?

To solve unknown values in a combination circuit, use series circuit rules for those sections of the circuit that are connected in series and parallel circuit rules for those sections connected in parallel. __circuit, the sum of the voltage drops of the individual resistors must equal the applied voltage.

How does resistance affect electric current?

The current is directly proportional to the voltage and inversely proportional to the resistance. This means that increasing the voltage will cause the current to increase, while increasing the resistance will cause the current to decrease.
