E=IR.....So, R=E/I........ E volts diveded by I amps= resistance.... You do the math...

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 are the componets that make up a circuit?
A circuit can have as little as two components 1 Must have a power source 2. Something for that power source to power, for example a light *Assuming you already know you need wires to complete the circuit
How much resistance is in the circuit if it uses a current of 0.01 A?
There is insufficient information in the question to properly answer it. You need to specify, also, the voltage, in order to determine resistance from current. Please restate the question. Ohm's Law: Resistance = voltage divided by current.
Why the power must be off when checking the resistance in the circuit?
an ohmmeter contains its own power source that it uses to test the circuit. if power is still on in the circuit, at the least the meter will give incorrect readings, at the worst the meter may be damaged rendering it useless.
What is the difference between electric soldering iron and ordinary soldering iron?
An electric soldering iron is heated by an electric resistance coil inside. Others may be heated either by a gas(like propane) flame, or by sticking them in a forge between uses.
What sentence uses the the words electric circuit in it?
The electric circuit has a current running through it.
Why remove resister from circuit to measure resistance?
a meter uses its own supply to measure resistance. you dont have to remove the resistor from the circuit but you must isolate it from the circuit supply to get an accurate reading.
What is a device in a circuit that uses electric to energy to do work?
load
What is an elecrtric circuits?
An electric circuit is just a circle of electric wires who connect all sorts of resistances (everything that uses electricity is called a resistance) and an electric source. Example: a battery connected to three lights: (each R represents a bulb) I hope this helps!
What does an electric blanket covert electrical energy to?
Heat. Electric blankets are simply a resistance coil, which convert electrical energy to heat.
What is an alternate name for an electric diagram?
There is no "proper name" for an electrical diagram. They are commonly called circuit diagrams.
What affects the amount of electric energy an appliance uses?
Its resistance.
How many watts does an electric drill use?
To figure that out you need to know the Amperage that it draws and what the voltage of the circuit is that you're using. Once you know that you can figure out how many watts it uses by doing simple math. Voltage x Amperage = Watts
What is an example of a load in a electric circuit?
Anything that uses electricity. For example, a light-bulb.
What is the load for a doorbell circuit?
The load on a door bell circuit is the coil of the ringer. It is dependant upon the coil resistance and the voltage the system uses. The equation to use is A = E/R, Amps = Volts/Resistance.
Why semiconductor is uses for most of the electronics circuit?
Semiconductors allow for the control of the flow of current and voltage by the use of resistance.
What are the uses of a piller drill?
To drill holes
