Ohms Law and Power
- Kom nrhiav qhov Voltage, (V) [V=I x R] V (volts)=I (amps) x R (Ω)
- Yuav nrhiav qhov tam sim no, (I) [I=V ÷ R] I (amps)=V (volts) ÷ R (Ω)
- Yuav nrhiav qhov Resistance, (R) [R=V ÷ I] R (Ω)=V (volts) ÷ Kuv (amps)
- Yuav nrhiav Lub Hwj Chim (P) [P=V x I] P (watts)=V (volts) x I (amps)
Koj suav qhov voltage li cas?
Tam sim no ntws tawm ntawm lub hwj huam mov tsuas yog voltage (5 volts) faib los ntawm tag nrho cov tsis kam, I=V / R, yog li: I=5R + RLED.
Tus qauv rau tag nrho qhov voltage yog dab tsi?
Tag nrho qhov hluav taws xob hauv ib lub voj voog yog sib npaug rau qhov sib npaug ntawm tus neeg qhov hluav taws xob poob ETag nrho=E1 + E2 +… En.
Tus qauv rau tam sim no thiab voltage yog dab tsi?
Cov lus piav qhia ntawm no yog qhov ntawd; Tam sim no sib npaug Fais fab faib los ntawm Voltage (I=P / V), Fais fab sib npaug Tam sim no lub sij hawm Voltage (P=VxI), thiab Voltage sib npaug Fais fab faib los ntawm Tam sim no (V=P / I).
tus qauv tam sim no yog dab tsi?
Qhov tam sim no yog qhov piv ntawm qhov sib txawv ntawm qhov muaj peev xwm thiab qhov tsis kam. Nws yog sawv cev raws li (I). Cov qauv tam sim no muab raws li I=V / R. SI unit ntawm tam sim no yog Ampere (Amp).
