Circuit Diagrams Differentiated Task Remember Series circuits are one continuous loop; parallel circuits have multiple paths 1 Identifying circuits (Apply) For the circuit on the right are the pairs of components connected in series or in parallel? a) R1, R2 b) L1, L2 c) R3, V2 d) R3, L2 e) A1, L1 f) g) A1, R3 h) R1, A2 2 R2, V1 Circuit rules (Revise) Use the words below to fill in the gaps (one of the words should be used twice). Then use the text to create revision flash cards containing versions of the rules in your own words. series parallel same split resistance added voltage In a ..................... circuit the current is the same all the way round. The total .................. supplied is split between the various components depending on their .................. . The total resistance of the circuit is the resistance of all the components .................. together. In a ............... circuit the voltage is the same in each path. The current can ..................... at a junction in the circuit. The current in each path is not always the ................... and depends on the ................... of the components in that path. 3 Voltage, current and resistance in circuits (Apply) For the circuit shown in Task 1, use the data in the table to calculate the following: a) total resistance of R1 and R2 Component b) current through A1, A2 Current (A) Voltage (V) Resistance () c) voltage on V1, V2 R1 0.3 1 0.33 d) total resistance R3 and L2 R2 0.3 0.5 1.67 e) total voltage supplied R3 0.15 0.45 3 f) L1 0.15 1.5 10 L2 0.15 1.05 7 voltage across L1 compared with the total voltage across R3 and L2.
