Engineers connect components in electrical circuits in series or parallel to make a range of useful circuits. ... When resistors are connected in series, the current through each resistor is the same.

National 5; Practical electrical and electronic circuits Calculating the value of the series resistor. Measurement and analysis of current and voltage in simple circuits allows us to formulate ...

An RC circuit in series with the coil allows full-current turn-on for reliable relay operation, ... All we do is add two common parts: a resistor and capacitor in parallel.
