Answer:
total resistance is 54.54 ohms
Step-by-step explanation:
In parallel circuits, current can take various paths so the resistance are not added simply like that in series circuit, instead the reciprocal of total resistance in parallel circuit is calculated by adding the reciprocals of all the resistors connected parallel in circuit.
Given:
Resistor r1= 100
resistor r2 = 200
resistor r3= 300
The three resistors are connected in parallel so the total resistance will be calculated by:
1/R= 1/r1 +1/r2 +1/r3
Putting the values of r1, r2, r3 in above we get
1/R= 1/100 + 1/200 +1/300
= 0.01 + 0.005 + 0.0033
= 0.0183
Taking reciprocal of both sides:
R=54.54
Hence total resistance is 54.54 ohms!
