THEORY
• In this circuit, for finding the voltage across resistors R1 and R2, we can use
the expression:
• For V1, V1=VR1/(R1 +R2)
• And for V2, V2=VR2/(R1 +R2)

4. Career Point Cares
• In this circuit, for finding the current across resistors R1 and R2, we can use
the expression:
• For I1, I1=IR2/(R1+R2)
• And for I2, I2=IR2/(R1+R2)

COMPONENTS USED
• Resistors
• Voltmeter
• Ammeter

6. Career Point Cares
Resistors
• Resistors are used to reduce the voltage.
• If they are used in series they cause voltage division
• And if they are used in parallel they cause current division

7. Career Point Cares
Voltmeter
• Voltmeter is used to measure the voltage across two terminals
• It is always connected in parallel because it contains resistance which can
reduce the voltage

8. Career Point Cares
AMMETER
• Ammeter is used in measuring the current across the circuit
• It is connected in series because it does not contain its own resistance

How circuit works
• When the switch is on, the voltage starts flowing through the circuit
• mA measures its current, then voltage goes through the resistor R1
• And the divided voltage can be seen in the voltmeter
• The same is applied on R2
• After that the mA measures the current again so that we can measure the
current division through the mA on each wire.
• Then current flows across the two more resistors which are connected in
parallel. In this ways we can calculated the divided current.
• If R2 is greater, then I1 will be greater, and when R1 is greater, then I2 will
be greater.
