Name _______________________________________________ Block _________ COMBINATION CIRCUITS 1. Determine which resistors are connected in series and which are connected in parallel. Solve for resistance using the appropriate formula. RT = R1 + R 2 + R 3 𝟏 𝟏 𝟏 𝟏 = + + 𝑹𝑻 𝑹𝟏 𝑹𝟐 𝑹𝟑 2. Redraw the circuit, replacing each of those series or parallel resistor combinations identified in step 1 with a single, equivalent-value resistor 3. Repeat steps 1 and 2 until the entire circuit is reduced to one equivalent resistor. 4. Calculate total current from total voltage and total resistance. 𝑰𝑻 = 𝑽𝑻 𝑹𝑻 Find the total resistance in each circuit. 1. 2. 3.
