How do you Calculate the voltage of a battery if the resistance is 20hms and the current is 0.35 amperes?
Use Ohm's law. V = I * R where V is voltage in volts, I is current in amperes, and R is resistance in ohms.
What is measured in amperes a current voltage or an Resistance?
Electrical current is measured in amperes.
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.
Three identical resistors each 45 ohms are connected in parallel across a 60-V battery The current through or drawn from the battery is?
If 3 identical 45-ohm resistors are connected in parallel, the net effective resistance of the bunch ...and the load seen by the battery ... is 15 ohms. The current supplied by the battery is60/15 = 4 Amperes.(This assumes that the battery is capable of supplying 4 amps at 60 volts, or 240 watts !)
A wire with resistance R is connected to the terminals of a 30 V battery. What is the current through the wire if the wire has the resistance?
Your current will be 30/R Amps. Where R is the resistance in 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.

Use Ohm's law. V = I * R where V is voltage in volts, I is current in amperes, and R is resistance in ohms.
How many amperes does a 6 volt DC battery put out?
That will depend on the sum of the load resistance and the internal resistance of the battery (this is true for all power sources, not just 6 volt batteries). Small compact batteries tend to have higher internal resistance and therefore are more limited in the current they can deliver to a given load than larger batteries.
A 9.0 volt battery is connected to a 4.0-ohm and 5.0-ohm resistor What is the current in the circuit?
If a 9.0 volt battery is connected to a 4.0-ohm and 5.0-ohm resistor connected in series, the current in the circuit is 1.0 amperes. If a 9.0 volt battery is connected to a 4.0-ohm and 5.0-ohm resistor connected in parallel, the current in the circuit is 0.5 amperes.
What is measured in amperes a current voltage or an Resistance?
Electrical current is measured in amperes.
What is the current in a copper wire that has a resistance of 3 ohms and is connected to a 9-volt electrical source?
3 amperes. Ohm's law: Voltage is ohms times amperes.
What is the current of a 1.5 volts battery?
That depends on the resistance connected. Use Ohm's Law: V=IR. Solving for current: I = V/R. If nothing is connected, there will be no current (infinite resistance).
A circuit has total resistance of 5 ohms and a current of 0.3 amperes What voltage must the battery supply?
1.5 volts
In a circuit with a 6 V battery hooked up to a 3 Ohm light bulb what does the current measure?
2 amperes (current = voltage/resistance)
What is the current in a 1.5V Alkaline battery?
The current depends on what is connected to the battery's terminals. If nothing is connected to it, then there is no current, and the battery lasts quite a while. In general, the current is 1.5/resistance of the external circuit connected to the battery until that number gets too big, and then the voltage of the battery sags, because it can't deliver that much current.
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.
Calculate the voltage of a battery if the resistance is 80 ohms and the current is 0.5 amp?
Ohm's law: Voltage is resistance times current. 80 ohms time 0.5 amperes = 40 volts.
