Ohm’s Law
Electrical Current is measured in ________ and represented by the letter ___
Voltage is the __________ in a circuit and is represented by the letter ____
Resistance is the _____________________ in a circuit, represented by the letter _____
and symbol _______
Current, voltage, and resistance are three elements or __________________ found in
every electric or electronic circuit no matter how simple or complex the circuit is.
Schematic symbols represent a circuit: Illustrate a battery and a resistor below
Ohm's Law establishes the relationship between voltage, current and resistance in a
circuit. This law states that the amount of ________________flowing in a circuit depends
upon the amount of ______________ in the circuit and the amount of ______________
in the circuit.
As the _______________ (v) increases, the current (I) _________________
Therefore, we can say that the current in the circuit is ___________________________
to the voltage in the circuit.
A larger voltage will produce a ________________ current, a smaller voltage will
produce a ____________________ current.
As resistance (R or Ω) increases, Current _________________
Therefore we can say that the amount of current in a circuit is
_________________________ to the amount of resistance, which means, the greater the
resistance, the smaller the ______________________, and the smaller the resistance, the
________________ the current. Now we can say that we have proven Ohm's Law.
Ohm's Law states that the current that flows in a circuit is _______________ proportional
to the voltage and ________________________ proportional to the resistance.
The mathematical formula for Ohm's Law is ___________________________________
We can use this formula to calculate the value of the _____________ flowing in a circuit
when we know the _________________ of the battery and the amount of the _________.
