Question

Problem 3. The reading on the ammeter in figure below is 3.00 A, and the current runs from right to 
left through the ammeter. 
(a)What is the value of current I1?
(b) Find the current I2.
(c)What is the emf  ? 

**Problem 3.** The reading on the ammeter in the figure below is 3.00 A, and the current runs from right to left through the ammeter. (a) What is the value of current \( I_1 \)? (b) Find the current \( I_2 \). (c) What is the emf \( \varepsilon \)? **Circuit Diagram Explanation:** The circuit consists of: - An ammeter measuring 3.00 A located in the middle of the circuit. - A 4.00 Ω resistor connected in series to a battery with an unknown emf \( \varepsilon \) on the upper branch. - The lower branch includes a 24.0 V battery connected to a 3.00 Ω resistor. - Both branches join at a junction before reaching the ammeter, which also has a 1.00 Ω resistor in series directly across it. The diagram suggests two currents: - \( I_1 \) flowing through the lower branch. - \( I_2 \) flowing through the upper branch. Direction of Currents: - Both \( I_1 \) and \( I_2 \) are shown to flow towards the node and converge across the ammeter.
