Parallel combination?

Question

In which time,we use Parallel combination of resistance?
Give answer with example.

Answer 1

For example in a voltmeter, you want to measure the resistance across a circuit element, but if this happens to be current-dependent (eg as across a resistor) you don't want to draw too much current through the voltmeter itself. So you use a large resistance in the voltmeter--much larger than the resistance you're supposedly measuring.

The situation is reversed in an ammeter--there you try to make the resistance as small as possible.

Whenever for some reason you want different currents but the same voltage, you use resistance in parallel.

Answer 2

We can use a parallel combination of a resistance, when you see resistors opposite each other. But, sometimes, there maybe resistors opposite each other and some next to each other. In that case, you have to use both parallel and series.
Hope that helps

Answer 3

when we have 2 high resistors but we need a smaller one in the circuit.but not always.it depends on the situation.
