mga boss
eto ung unang nabanggit ni boss radz
tungkol sa coc examination
dugtungan nyo nalang po kung kulang
ohm's Law
Next Page: Power and Energy
Also See: Voltage and Current | Resistance | Resistors
To make a current flow through a resistance there must be a voltage across that resistance. Ohm's Law shows the relationship between the voltage (V), current (I) and resistance (R). It can be written in three ways:
V = I × R or I = V
R
or R = V
I
where: V = voltage in volts (V)
I = current in amps (A)
R = resistance in ohms ( ) or: V = voltage in volts (V)
I = current in milliamps (mA)
R = resistance in kilohms (k )
For most electronic circuits the amp is too large and the ohm is too small, so we often measure current in milliamps (mA) and resistance in kilohms (k ). 1 mA = 0.001 A and 1 k = 1000 .
The Ohm's Law equations work if you use V, A and , or if you use V, mA and k . You must not mix these sets of units in the equations so you may need to convert between mA and A or k and .

You can use the VIR triangle to help you remember the three versions of Ohm's Law.
Write down V, I and R in a triangle like the one in the yellow box on the right.
• To calculate voltage, V: put your finger over V,
this leaves you with I R, so the equation is V = I × R
• To calculate current, I: put your finger over I,
this leaves you with V over R, so the equation is I = V/R
• To calculate resistance, R: put your finger over R,
this leaves you with V over I, so the equation is R = V/I |
