∙ 14y agoThe effective resistance of the combination is the reciprocal of [ (1/20) + (1/60) + (1/40) ].
(1/20) + (1/60) + (1/40) = (6/120) + (2/120) + (3/120) = (11/120)
The effective resistance is (120/11) = 10.91 ohms(rounded)
It makes no difference what the resistors are connected across, or what its voltage is, or
whether it's another passive network, or whether they're connected across anything at all,
or whether they've sunk to the bottom of the parts drawer. Their effective resistance is
still roughly 10.91 ohms.

It doesn't matter what else is in parallel with the 60-ohm resistor, as long as the power supply
is capable of the total current in all three branches, and the 120 volts doesn't 'sag'.

A 120 ohm resisto a 60 ohm resistor and a 40 ohm resistor are connected in parallel to a 120 volt power source What is the current running through the 60 ohm resistor?
If they're in parallel, then each resistor acts as if it were the only one,and the presence of any others is irrelevant.The current through the 60-ohm resistor is I = E/R = (120/60) = 2 amperes.
A 120 ohm resistor a 60 ohm resistor and a 40 ohm resistor are connected in parallel to a 120 volt power source What is the current running through the 120 ohm resister?
If they're in parallel, then the resistors have no effect on each other. The current through each one is the same as it would be if the others were not there at all. The current through the 120Ω resistor is 120 volts/120Ω = 1 Ampere. The 60Ω and the 40Ω are red herring resistors.
A 120 ohm resistor and a 40 ohm resistor are connected in parallel to a 120 volt power source what is the current running through the 40ohm resitor?
The current through the 40-ohm resistor is ( E / R ) = (120 / 40) = 3 amperes.The current through the 40-ohm resistor doesn't depend on the 120-ohm resistor. It's the samewhether the 120-ohm is there or not. It would also be the same if there were any other resistor,with any other resistance, connected in place of the 120-ohm resistor. It would also be the sameif there were 3,000 more resistors in parallel, with all different values of resistance (as long asthe whole conglomeration didn't exceed the capabilities of the power source).
Why 2 alternator running in parallel have voltage same but ampere different?
Let's say both Alternators are 24V. If you put them is series, you are adding the potential, or electrical pressure. Putting them in parallel keeps the pressure the same, but you added another path for current (amps).

How current passes through resistor.?
What is the current running through resistor four?1 amps..!What is the current running through resistor one? 3 amps...!What is the current running through resistor three? 2amps..!What is the current running through resistor five? 3 amps..!What is the voltage drop running through resistor five? 45 volts...!What is the equivalent resistance through the parallel portion of the circuit? 6 ohmsAnswerA resistor is a conductor, albeit one with a higher resistance than a length of wire, so current passes through it without any problem. The magnitude of the current will, of course, be somewhat lower because of the additional resistance.

Resistors do that when there's a current running through them.
Are two toy electric trains running on the same track connected in series or parallel?
Two toy electric trains running on the same track are connected in parallel because they both get energized from DC impressed across the two rails they ride on.
