Two resistors are connected in parallel. (a) Ifa third resistor is now connected in parallel with the original two,does the equivalent resistance of the circuit increase, decrease, orremain the same? (b) Choose the best explanation from among thefollowing:I. Adding a resistor generally tends to increase the resistance,but putting it in parallel tends to decrease the resistance;therefore the effects offset and the resistance stays the same.II. Adding more resistance to the circuit will increase the equivalent resistance.III. The third resistor gives yet another path for current to flow inthe circuit, which means that the equivalent resistance is less
Ohm's law
Ohm’s law is a prominent concept in physics and electronics. It gives the relation between the current and the voltage. It is used to analyze and construct electrical circuits. Ohm's law states that the voltage across a conductor is directly proportional to the current flowing through it.
Path of Least Resistance
In a series of alternate pathways, the direction of least resistance is the actual or metaphorical route that offers the least resistance to forwarding motion by a given individual or body.
Two resistors are connected in parallel. (a) If
a third resistor is now connected in parallel with the original two,
does the equivalent resistance of the circuit increase, decrease, or
remain the same? (b) Choose the best explanation from among the
following:
I. Adding a resistor generally tends to increase the resistance,
but putting it in parallel tends to decrease the resistance;
therefore the effects offset and the resistance stays the same.
II. Adding more resistance to the circuit will increase the equivalent resistance.
III. The third resistor gives yet another path for current to flow in
the circuit, which means that the equivalent resistance is less
