5 amps.
Use Ohm's Law:
I = V/R = 90/18 = 5
...90 volts...
Using Ohms Law, the answer is 120/0.5 = 240 Ohms.
you divide the volts by the ohms
Ohm's law: Voltage equals current times resistance. 8 amperes times 24 ohms equals 192 volts.
The capital Greek letter Ω (omega) is the symbol for Ohms - the unit of resistance. A 1.5Ω resister is a resistor with quite a low resistance. If a voltage of 1.5 Volts is applied across it, a current of 1 Amp[ere]s will flow through it.
To find the current running through the devices, you can use the formula ( I = \frac{P}{V} ), where ( I ) is the current in amperes, ( P ) is the power in watts, and ( V ) is the voltage in volts. Given the power rating of 440 watts and a voltage of 110 volts, the current can be calculated as ( I = \frac{440}{110} = 4 ) amperes. Therefore, the current running through the devices is 4 amps.
Total resistance (thevinen resistance) = 4 + 8 Total voltage = 12 volts. Ohms law: I = V / R Therefore I = 12/12 = 1 amp.
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.
Volts cause current to flow through the load. The current is measured in amps, and the volts multiplied by the amps gives the power in watts.
What is the voltage drop running through resistor one
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.
To work this out you will need to know the current that is travelling through the device. You can then find the number of volts by dividing the power (watts) by the current (amps).
