What power is converted when the applied voltage is doubled? 20 W 10 W 5 W 7,25 W 15 W Which statement agrees with the resistance curves shown below? Resistors curves R2 > R1 R1 = R2 R3 < R2 R2 > R3 R3 < R2 R1 > R3 Which statement about the circuit below is correct? Resistors – Mixed connections The current through R2 is half the current through R4. The current through R3 is twice the current through R4 The currents through R1 and R4 are equal The current through R4 is half the current through R3 The current through R3 is twice the current through R2 Resistors of different sizes are connected in parallel. Which statement is correct? The largest partial current flows through the smallest single resistor The current in the entire circuit is the same The total resistance is bigger than the smallest single resistance The total resistance is equal to the sum of the single resistances The total voltage is equal to the sum of the individual voltages How does the power behave when the resistance is halved? The power is squared The power remains the same The power doubles The power is halved The power triples Loading … < Previous Page | Next Page >
