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.

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.
The equivalent resistance of the three resistors…
