Think it through. You are adding a second path for current flow.
Current flow will increase to some extent.
Therefore, with more current flow, resistance must....

What resistance must be connected in parallel to 6.0-ohm resistor to reduce the combined resistance to 15-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.
Voltmeter is connected in parallel with resistor?
A voltmeter can be connected in parallel with a resistor to show the voltage across the resistor.
How should voltmeter be connected to measure the potential difference across a resistor - in series or in parallel?
In parallel.
If a 15-ohm resistor is connected in parallel with a 30 ohm-resistor the equivalent resistance is?
Rt = 10
When a 1 ohm resistor and a 1 ohm resistor are connected in series what is their conbined resistance?
The combined resistance will be 2 Ohms.

What happen if 4 resistor is connected in parallel and resistor 1 is connected as short circuit?
I'd have to see a diagram, as your description in words is unclear.

When 2 resistors are connected in parallel r1r2 are?
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.
What will happen to the other resistor if the number of resistor decreases?
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.
When a 1 ohm resistor and a 1 ohm resistor are connected in series what is their conbined resistance?
The combined resistance will be 2 Ohms.
What type of meter is connected in parallel with a resistor in a circuit and why?
A voltmter, to measure potential diffrence
What is the configuration of the ohmmeter?
An ohmmeter is connected in parallel to a resistor. Be sure that there is no power in the circuit when testing.
What is a resistor bank?
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.
How you convert galvanometer into ammeter in detail?
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.
