20k is equal to 20,000 ohms (20 kilo ohms) and 200k is equal to 200,000 ohms (200 kilo ohms) of electrical resistance
Nine tenths of the voltage would appear across the 200-ohm coil.
A 10 ohm resistor across a 20 volt source has 2 amps flowing through it. A 20 volt source providing 2 amps is producing 40 watts. Voltage is Resistance times AmperesWatts is Voltage times AmperesAlternative AnswerDivide the square of the voltage by the resistance.
Ohm's Law Volts = Current x Resistance Amps = V / R 110 / 20 = 5.5 Amps
Remember Ohm's Law ; V = IR That is volts = amps(current) X Resistance. Algebraically rearrange R = V/I V = 20 volts I = 200 mA = 200/1000 Amps = 0.2 amps. Hence R = 20 V / 0.2 Amps R = 100 Ohms
Total resistance is 120 ohms. The 120VAC will be split evenly over this 120 ohm load, so every ohm of resistance gets a volt. So there will be a 40 volt drop across the 40 ohm resistor.
200 is ten times as big as 20.
5 ohms
-- If the 20 ohms and the nother 10 ohms are configured in series, then the totalnet effective resistance is 30 ohms.-- If they are configured in parallel, then the total effective resistance is 62/3 ohms.
5 A
A 1 ohm 20% tolerance resistor should not exceed 1.2 ohms actual resistance.
20k is equal to 20,000 ohms (20 kilo ohms) and 200k is equal to 200,000 ohms (200 kilo ohms) of electrical resistance
200 millimetres
Nine tenths of the voltage would appear across the 200-ohm coil.
Ohm's Law: Voltage is equal to current times resistance 0.002 amperes times 10,000 ohms equals 20 volts.
For an end-result of 10 ohms, you can have 1 resistance of 10 ohms, or 2 parallel resistance of 20 ohms each, or 3 resistances of 30 ohms each, etc.
