When unequal resistors are connected in parallel in a circuit,
The potential drop is always the same across each resistor
An ideal ammeter should
introduce a very small series resistance into the circuit whose current is to be measured
When unequal resistors are connected in series across an ideal battery,
the current flowing in each is the same.
Kirchhoff's loop rule is a statement of
the conservation of energy
You buy a AA battery in the store, and it is marked 1.5 V. If this marking is strictly accurate, while this battery is fresh
its terminal voltage will be less than 1.5 V when it is used in a circuit.
Four unequal resistors are connected in a parallel with each other. Which one of the following statements is correct about this combination?

The equivalent resistance is less than that of the smallest resistor.
The equivalent resistance is equal to the average of the four resistances.
The equivalent resistance is midway between the largest and smallest resistance.
The equivalent resistance is more than the largest resistance.
None of the other choices is correct.
The equivalent resistance is less than that of the smallest resistor.
As more resistors are added in series to a constant voltage source, the power supplied by the source
decreases.
