C7802 Ohms Law 2005_newer
... Voltage is the force or electric pressure that allows current flow. It is measured in volts. The letter “V” (or sometimes “E”) is used to represent voltage. Resistance is the opposition to current flow. It is measured in ohms (Ω). The letter “R” is used to represent resistance. Current (I), voltage ...

Proportion of Voltage to Resistance in a Series Circuit
... A series circuit is shown in the diagram above. V represents the total voltage and I represents the current. The three sets of jagged lines represent resistors with resistances represented by the variables R1, R2 and R3. Resistance is measured in ohms, represented by the symbol Ω. ...

Resistors Connected in Series and in Parallel
... How are resistances R2 and R3 connected in the resistance network shown at the right? They are not connected in series, because the current through R2 is not necessarily the current through R3 (why?) R2 and R3 are connected in parallel because the potential drop across R3 is the same as the potentia ...
