There is a resistance line. If the current in the resistance line is 0.5A when 6V voltage is applied at both ends, the resistance of the resistance line is______ Ω, if the voltage of 12V is applied at both ends, the current passing through the resistance line is______ A. The resistance of the resistance wire is______ Ω; if there is no voltage at both ends of the resistance line, the current through the resistance line is______ A. The resistance of the resistance wire is______ Ω．

The resistance of the resistance wire r = UI = 6v0.5a = 12 Ω; when the voltage of 12V is applied at both ends, the current I ′ = u ′, r = 12v12 Ω = 1A; the resistance of the conductor remains 12 Ω; when the voltage of both ends is 0, the current through the resistance wire is 0; the resistance of the resistance wire remains 12 Ω; so the answer is: 12; 1; 12; 0; 12

Connect the fixed value resistor with a resistance value of 10 Ω to the voltage of 6V, and the current passing through the fixed value resistor is 0.6A. When the voltage at both ends of the fixed value resistor becomes 12V, it passes through the fixed value resistor
The current in the value resistor is ----- a. the resistance of the constant value resistor is ----- Ω

The resistance value of the resistor is unchanged, it is still 10 Ω, and the current in the constant value resistor is I = u / r = 12V △ 10 Ω = 1.2A
