The 3 basic formulas for Ohm's Law are :
Ohm's Law: Current = Voltage divided by resistance 9 volts divided by 3 ohms = 3 amperes.
You have to convert all values to ohms. 3 kiloohms = 3000 ohms. 3 micoohms = three millionth of an ohm = 0.000003 ohms. The product is: 3000 times 0.000003 = 0.009 ohms squared.
3000 ohms are 3 kiloohms.
Mega is 8 X 10^6 and Kilo is 8000 X 10^3. For every 3 you go down in powers you divide by 1000, so 8 Mega ohms is 8,000,000 ohms. 8,000 Kilo ohms or 0.008 Giga ohms.
The current in the circuit will depend on how the three resistors are wired. Series? Parallel? Series parallel? With the resistors in series, 3, 2 and 4 ohms will add to 9 ohms. As I = E/R, I = 9 V / 9 ohms = 1 A. With the resistors in parallel, the 3, 2 and 4 ohm resistors will draw 3 A, 4.5 A and 2.25 A respectively, and the total current will be the sum of the branch currents, or 3 A + 4.5 A + 2.25 A = 9.75 A. There are 3 different series parallel circuits possible, and more investigation will be necessary to solve for them.
Ohm's Law: Current = Voltage divided by resistance 9 volts divided by 3 ohms = 3 amperes.
ohms law
3 amperes. Ohm's law: Voltage is ohms times amperes.
ohms law states V = I*R; V = (.005)(1000) = 5volts.
V = I * R V = voltage I = curernt R = resistance
You have to convert all values to ohms. 3 kiloohms = 3000 ohms. 3 micoohms = three millionth of an ohm = 0.000003 ohms. The product is: 3000 times 0.000003 = 0.009 ohms squared.
3000 ohms are 3 kiloohms.
It will take 36 volts to make 12 amps go through 3 ohms of resistance. Ohm's law states that the current in amperes is equal to voltage over resistance.
Ohm's Law: Resistance = voltage / current, so 12 / 3 = 4 ohms.
(3 x 103) x (3 x 10-6) = 0.009 squared ohms ... a quantity with no physical significance
Just use Ohm's Law: V=IR (voltage = current x resistance; using units: volts = amperes x ohms).
Mega is 8 X 10^6 and Kilo is 8000 X 10^3. For every 3 you go down in powers you divide by 1000, so 8 Mega ohms is 8,000,000 ohms. 8,000 Kilo ohms or 0.008 Giga ohms.
