Remember, voltage is read in parallel (outside of the circuit), while current isread in series (in the circuit)
Part I: DC Circuits in SeriesBuild a simple circuit made of one battery and one light in a single loop.1.Use a voltmeter to find the voltageacross the light. Light: ________________ Volts2.Use an ammeter to find the current through the lightbulbLight: ________________ Amps3.Use Ohm’s Law IRVto find the resistance of the lightLight: ________________ Ohms4.Set both of the voltmeter’s probes on the same side of a light. What is the voltage? _____ Why? ________________5.Reverse the battery (right click on it and choose reverse). What happens to the flow of electrons? ______________________________________________6.Build a circuit with a battery and three lights in seriesWhat are the voltages across each item in the circuit?(.5 pts each)Light 1: ________________ VoltsLight 2: ________________ VoltsLight 3: ________________ VoltsBattery: ________________ Volts..
7.What is the current in each part of the circuit? (.5 pts each)Between Battery and Light 1: _____________ AmpsUse Ohm’s Law to find the resistance of the lightsBetween Lights 1-2: __________________ AmpsLight 1: ________________ OhmsBetween Lights 2-3: __________________ AmpsLight 2: ________________ OhmsLight 3: ________________ Ohms8.Are all the lights the same brightness? _______9.Add additional batteries in series with the first battery. (making sure you connect the positive of one battery to the negative of the next battery). What happens to the brightness? _________________the voltages? _________________the currents? _________________10.Add a resistor to your series circuit.What effect did the resistor have on the lights in the circuit? _________________________________________________11.Create a wire path in your circuit that bypasses all the lights. This is a short circuit.
