voltage divider in action


 

Resistors can be used also to reduce the voltage supplied to different parts of a
circuit.


»» One 6-volt battery (4*1.5)
 »» jumper wire
 »» One 2.2 kΩ resistor

»» One 3.3 kΩ resistor
 »»breadboard
 

Next, use your multimeter set to volts DC to measure the voltage across the bat-
tery and across the resistors. My measurements
show that the actual battery voltage is 4.8 V
Vout (the voltage across the 2.2kΩ resistor) is 1.9 V. and
Vout (the voltage across the 3.3kΩ resistor) is 2.9 V. and

Kirchhoffs Voltage Law

Image
  Kirchhoffs Voltage Law or KVL, states that “in any closed loop network being driven by a voltage source, the total voltage around the loop is equal to the sum of all the voltage drops within the same loop” which is equal to zero. 1. Two led series circuit Voltage across battery: 6 volts Voltage across resistor: 2.4 volts Voltage across led1: 1.8 volts Voltage across led2: 1.8 volts

Limiting current

Image
  I used 3 type of resistor  3.3KΩ - 2.2kΩ - 1kΩ parallel circuit  in which each branch contains a different value of resistance. For higher values of resistance, the cur- rent that passes through that branch is restricted more, so the LED in that branch emits less light.
