E/R=I. 100/50=2 amps.
Diodes are rated to use a certain amount of current. If you go over that amount, it will eventually destroy the device, how long it takes to destroy the device depends on how much more current you are running through it than it is rated at.
It depends on the resistance of everything connected between the terminals of the power supply. If the resistance is infinite or very high, there is little or no current. As the resistance becomes less, the current becomes greater. In general, the current through a circuit with 90 volts applied to it is [ 90 / R ], where 'R' is the resistance of everything across the 90-volt power supply.
The resistor bypass in the ignition circuit is used when starting the engine. It bypasses the resistor to provide full battery voltage to the ignition coil, ensuring a strong spark for a quick and reliable engine start. Once the engine is running, the bypass is no longer needed and the resistor is re-engaged to limit the voltage to the ignition coil for normal operation.

There is insufficient information in the question to properly answer it. You need to provide more information, such as the voltage across resistor four, or more details about the rest of the ciricuit. Please restate the question.

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.

To find the current running through the circuit, you need to use Ohm's Law, which states that the current flowing through a conductor between two points is directly proportional to the voltage across the two points, and inversely proportional to the resistance between them. You can use the following formula to calculate the current: I = V / R Where I is the current, V is the voltage, and R is the resistance. In this case, the total resistance of the circuit is the sum of the individual resistances, which is 5 ohms + 20 ohms + 25 ohms = 50 ohms. Therefore, the current flowing through the circuit is: I = 100 volts / 50 ohms = 2 amps.

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.
I'm having some trouble focusing in on the schematic of the circuit.

Resistors do that when there's a current running through them.
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).
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.
The electric circuit has a current running through it.
