The voltageVis equal to the currentIin amps times the resistanceRin ohms. For example,let’s find the voltage of a circuit with 1.2 amps of current and 20 ohms of resistance. V(V)= 1.2 A ÷ 20 Ω V(V)= 24 V A
Impedance is a measure of the electrical resistance of components, given in ohms. We use impedance among other things to determine compatibility betweenamplifierandspeaker boxes. Speakers are often rated between 4 and 8 ohms. Many amplifiers work best in the 6 to 12 ohm range. Let's make it ...
0 dBV equals 2.2 dBu or 0 dBu equals −2.2 dBV. The conversion from level L(dBu) to voltage (volt) is V = 0.775 × 10(L/20). The conversion from voltage V (volt) to level (dBu) is L = 20 × log (V/0.775).All field quantities, like voltage or sound pressure are always ...
It's the time it takes the TLC5947 PWM counters to count from zero to 4095, thereby completing the 12-bit PWM cycle. The PWM oscillator internal to the TLC5947 runs at 4 MHz under normal operating conditions. The period of the 4 MHz oscillator times 4,096 equals 1,024 microseconds. Si...
