Your toaster has a power cord with a resistance of 1.9×10−2 Ω connected in series with a 9.7 Ω nichrome heating element. The potential difference between the terminals of the toaster is 120 V. How much power is dissipated in the power cord? (W) How much power is dissipated in the heating element? (kW)
A certain toaster has a heating element made of Nichrome resistance wire. When the toaster is first connected to a 130-V source of potential difference (and the wire is at a temperature of 20.0°C), the initial current is 1.70 A, but the current begins to decrease as the resistive element warms up. When the toaster reaches its final operating temperature, the current has dropped to 1.53 A. (a) Find the power the toaster converts when it is at its operating...
Your toaster has a power cord with a resistance of 1.8×10−2 Ω connected in series with a 9.9 Ω nichrome heating element. The potential difference between the terminals of the toaster is 120 V. Part A How much power is dissipated in the power cord? Express your answer using two significant figures. Pcord= W Part B How much power is dissipated in the heating element? Express your answer using two significant figures. Phe= kW
Write a C program that finds voltage drop and power dissipated by a resistance (R) when a current (I) flows through it. Resistance and current values are given as inputs. Create a function that would find the voltage drop, and create another function that would find the power. Use these functions in your program and print the voltage drop and power dissipated on the console. The input and output values are single precision floating-point values. Comment your code.
In the circuit shown in the figure, find the power dissipated in the 3 resistance. In W.2 significant figues 20 +3V - 30 +6V w --- 6Ω +3V Hitt
