A student sets up a circuit containing a battery of two cells and three lamps, as shown.
What is the circuit diagram for this arrangement?
If you are not getting this, means you need to revise.
What is the resistance of this combination?
A 0.14Ω B 0.58Ω C 1.7Ω D 7.0Ω
Combined Resistance in parallel = 1 / R1 + 1 / R2
Then the fraction you get, make it upside down (means take denominator up and numerator down) and you will get the answer.
You have to use the calculator to calculate this answer.
A 3.0Ω resistor and a 6.0Ω resistor are connected in parallel.
What is their combined resistance?
A 0.50Ω B 2.0Ω C 4.5Ω D 9.0Ω
Two resistors are connected in parallel.
Which value could be the resistance of the combination?
A 12Ω B 20Ω C 25Ω D 50Ω
If you are not getting it, that means you need to revise.
A student connects various resistors in parallel pairs.
Underneath each diagram is a statement about the total resistance of each pair of resistors.
Which statement is correct?
Two resistors, with resistances R1 and R2 are connected in parallel.
The resistance R1 is greater than the resistance R2.
What is the resistance of the Parallel combination?
The reading on the ammeter in the circuit is 1.0A.
A second ammeter is connected in the circuit. It also reads 1.0A.
At which labelled point is it connected?
