The total resistance would be 40 ohm.
No such resistor exists. Any resistor placed in parallel with a 6.0 ohm resistor is going to reduce the combined resistance below 6.0 ohms.
Rt = 10

In simple way resistor bank contains number of resistors in series or parallel combination. They are connected in parallel to decrease the resistance and increase current rating and power dissipation.And they are connected in series to increase resistance and power dissipation.
A voltmeter can be connected in parallel with a resistor to show the voltage across the resistor.
Two resistors connected in parallel are 1/2 the sum of their resistance. The resistance of two resistors connected in series is the sum of their resistance. For example: The total resistance of a 100 ohm resistor connected to a 200 ohm resistor in parallel is 100+200 divided by 2 = 150 ohms. The total resistance of a 100 ohm resistor connected to a 200 ohm resistor in series 100+200= 300 ohms.
No such resistor exists. Any resistor placed in parallel with a 6.0 ohm resistor is going to reduce the combined resistance below 6.0 ohms.
Rt = 10
By attaching a resistance in parallel connection with the galvanometer. Or when a low resistor connected in parallel with galvanometer ,the galvanometer is converted in ammeter. and the resistor is called shunt resistance.
the voltage across that resistor will increase if it is in series with the other resistors. the current through that resistor will increase if it is in parallel with the other resistors.

half of the current flowing thru resistor 1.... V=IR.
When a resistor is added the current goes down, that is expressed in the equation current= voltage/ resistance
The effective resistance of those three resistors in parallel is 20 ohms. And it makes no difference what the power source is, or whether they're even connected to a power source at all. As soon as those three resistors are in parallel, their effective resistance is 20 ohms immediately, even if they're still in the drawer.
if we remove a resistor from the parallel connection the effective resistance value will be increased.
