CETT 1302 Electricity Principles Series Circuit Practice Problems 1. A 55.0Ω resistor and a 80.0 Ω resistor are connected in series and placed across a 45.0-V battery. a) What is the equivalent resistance of the circuit? b) What is the value of the current in the circuit? c) What is the potential drop (voltage) across the 55.0 Ω resistor? 2. Three resistors of 2 Ω, 5 Ω and 3 Ω are connected in series across a 5-V battery. a) What is the equivalent resistance of the circuit? b) What is the current through the resistors? c) What is the voltage drop (potential drop) across each resistor? 3. A 20.0 Ω resistor and a 40.0 Ω resistor are connected in series and placed across a 120-V potential difference. a) What is the current in the circuit? b) What is the voltage drop (potential drop) across each resistor?   the current in every part of the circuit (is the same, adds up).   the voltage supplied by the battery is the _______ voltage of the circuit, and the voltage drops across each resistor (is the same, adds up to) the total voltage.   to calculate total resistance, (add, use reciprocals).
