Assume you have a series circuit. The total resistance is 220Ω and the total voltage is 9 volts. What is the total current?
+561 The ratio between voltage potential difference and current will be equal to resistance, assuming the circuit is ohmic.
Therefore, we can calculate current with the following equation:
\(R=\frac{V}{I}\)
Where R is resistance, V is potential difference, and I is current.
In your question's case we would use it as shown:
\(220=\frac{9}{I}\)
\(I=\frac{9}{220}\)
\(I=0.041A\)
(Please don't call it voltage. Volts are the units of potential difference. It's like calling distance "meterage" or time "secondage".)
