If the battery in the circuit below is 9.78V, resistor R₁-217.51, and resistor R₂=160.920, what is the magnitude of the current flowing through the circuit? Please give your answer in units of milli-Amps (mA). R₁ A I R₂ HE + E B Note: It is understood that the unit of your answer is in milli-Amperes (mA), however do not explicitly include units in your answer. Enter only a number. If you do enter a unit, your answer will be counted wrong.
