What is the current read by the ammeter in the circuit below? Let R1 = 1 kiloohm, R2 = 2 kiloohm, R3 = 3 kiloohm, and the emf of the ideal source is 5 volts. Input R1, R2, and R3 for resistors R1. R2, and R3 respectively. Input E for the emf E. Use context clues to figure out if you need to input a numerical value, variable, word, etc. All numerical answers should be in three significant figures. R| R2 R3 First we calculate the current across each resistor. From Ohm's law, we arrive at a general formula for current: Plugging in values, the current across the resistor R1 is equal to: (Please note that the current is milliamperes) Similarly the current across R2 is: 12= mA And the current across R3 is: 13 = mA The current read by the ammeter is the sum of the currents across each resistor: 1=h+/2 +13 |= Alternatively, we can solve for the current across the ammeter by first calculating the equivalent resistance and then applying Ohm's law.
