Series Resistive Circuits
Define resistance - ANS-R is the opposition a material offers to current flow due to its
structure.
R is the property of a circuit or device that opposes a flow of current
Describe properties of resistance when their is higher resistance - ANS--flow of current
is restricted
-The voltage drops from one side and increased on the other
-The more resistance in a circuit the more opposition to flow
Described potential difference - ANS-An electrical current can only flow beteen two
points if there is an electrical difference
How does a ohmmeter measure resistance - ANS-Uses a small electrical current to
check the continuity of a circuit and resistance ina circuit in motors, cables or fuses
How is potential difference measure? - ANS-Measured in Volts m(V)
How is resistance (R) measured - ANS-Ohms
How is voltage measured in a closed circuit - ANS-Applied voltage is measured and
then the voltage drops across each resistor are measured
The applied voltage must equal the sum of the voltage drops
How to calculate total resistance in a series circuit with 4 resistors -
ANS-R1+R2+R3+R4= total resistance
How to measure a current - ANS-Connect an ammeter in a series with the circuit
element that you want to measure
How to measure the difference between two points in a circuit - ANS-To measure two
points connect the two leads of the voltmeter to those points
How to measure the voltmeter across a device like a resistor or the applied voltage -
ANS-To measure the voltmeter across a resistor or applied voltage connect the two
terminals of the voltmeter to the two ends of the resistors or across the voltage source
