(1) Because the two resistors are connected in series, the current I 1 flowing through R 1 is equal to the current I2 flowing through R2, and both of them are equal to the current expression, that is, I1= I2 = I = 0.4a;
According to ohm's law:
The voltmeter indicates v1:u1= I1r1= 0.4a×10ω = 4v.
(2) Resistance value of resistor R2:
R2 = u2i 2 = 2.4v 0.4a = 6ω
Answer: The indication of voltmeter V 1 is 4V; (2) The resistance of resistor R2 is 6 Ω.
