Current I = V/R
V = 9V
R = 100ohm
I = 9V/100ohm = 90mA

What is the Definition for ohms?
Ohm is the unit for electrical resistance. The definition is given by Ohm's Law: resistance = voltage / current; in SI units: ohms = volts / amperes. For example, a resistance of 1 ohm would result in 1 ampere of current for every volt applied.
A 3 Volt battery sends a current of 0.10 A through a light bulb what is the resistance of the filament of the bulb?
Volt (V) = Resistance (R) times Current (I) therefor R = V / I 30 Ω = 3V / 0.1A
How do the currents produced by a 1.5 volt flashlight cell and a 12 volt car battery compare if the resistance is the same?
12/1.5= 8. If I = Current from 1.5 Volt source and I2 = current from 12 V source then I = I2/8 or said in another way the current from 1.5V device is 1/8 of the current from 12 V device.
How many mA in total when four AA batteries of 1.5 volt is combined?
depending on your load resistance what are you using . suppose you are using 100 ohm load resistance than current will flow 1.5*4=6/100=0.06Amp and if you are looking for battery current capacity than mind it you are using series connection the current will not change remain same as one battery but voltage will change as i mention above 6 volt.
Who is law states that it takes one volt to push one amp through 1 ohm of resistance?
Ohms Law.
Actual internal resistance of 1.5 volt battery?
The value of internal resistance of 1.5 volt battery is 0.5 ohms.
When a 12 volt battery is connected across an unkown resistance there is a current of 2.5m amphere in the circuit find the value of resistance of the resistor?
4.8 ohms
How much current and circuit that includes a 9- volt battery and a bulb with a resistance of 3 ohms?
A resistance of 3 ohms connected between the terminals of a 9-volt battery will result in a current of 3 Amperes. If the battery is one of those little ones with snaps on top, it may be able to produce 3 amperes of current for about 3 seconds before it rolls over and totally dies.
What does ohm sign symbolize?
The ohm is the unit of electrical resistance to current flow. More ohms (more resistance), the less current will flow. Less ohms (less resistance), the more current will flow. One ohm is defined as the amount of resistance that will cause one ampere of current to flow if the supply voltage is one volt. Ohm's law states that amps = volts / ohms So, if you had a 12 volt battery, and you connected a load, say a heating element that had a resistance of 3 ohms, how much current would flow in the circuit? amps = 12 volts / 3 ohms amps = 4
A resistance of 10 ohms is placed across a 9 volt battery what current flows through the battery?
No current flows through the battery. There is a current through the external circuit. I = E/R = 9/10 = 0.9 amperes.
What is the current produced with a 9-volt battery through a resistance of 100 ohms?
Current I = V/R V = 9V R = 100ohm I = 9V/100ohm = 90mA
What resistance would produce a current of 120 amps from a volt battery?
Google Ohms Law. It will give you all the formulas you need to compute Ohms,Volts and Amps. Simple formulas :-)
How much current is in a circuit that includes a 9-volt battery and a bulb with a resistance of 12 ohms?
Current = voltage/resistance If those are the only components in the circuit, then Current = 9/12 = 0.75 Ampere = 750 mA
How much resistance is in the circuit if it uses a current of 10ma?
Just use Ohms Law: V=IR, that is, voltage (in Volt) = current (in Ampere) x resistance (in Ohms).
What is the resistance of 150-volt lamp with a current of 2amps?
75 ohms. R = E/I.
How much curretn is in a circuit that includes a 9- volt battery and bulb with a resistance of 12 ohms?
Current, I is equal to V (voltage) divided by R (resistance); Hence: I=V/R = 9V/200 ohms: I = 0.045 Amps, or 45ma (milliamps).
A 9.0 volt battery connected to bulb. if a current of 0.25 Amps flows through bulb what is the resistance of bulb?
V = IR Voltage = Current * Resistance so 9 = 0.25 * R Hence R =36 Ohms
