Ohm's law is the single most-used relationship in electronics: the voltage across a resistor equals the current through it times its resistance, V = I × R. Rearranged, the current is I = V / R and the resistance is R = V / I. Power — the rate at which the component turns electrical energy into heat or work — adds a second relationship, P = V × I, which combines with Ohm's law to give the two equivalents P = I² × R and P = V² / R. Together these four quantities form the V–I–R–P 'Ohm's law wheel', and knowing any two of them fixes the other two.
This calculator lets you pick which quantity to solve for and enter any two of the others, then returns the full wheel plus the three equivalent power formulas side by side. For example, a 12 V supply driving a 6 Ω resistor gives I = 12 / 6 = 2 A and P = 12 × 2 = 24 W; check it with P = I² × R = 4 × 6 = 24 W and P = V² / R = 144 / 6 = 24 W, all agreeing. Because the tool back-fills every missing value, entering power and current instead is just as valid — 24 W at 2 A returns 12 V and 6 Ω.
Ohm's law holds exactly for any DC resistive circuit and for the resistive part of an AC circuit, which makes it the everyday tool for sizing current-limiting resistors, choosing LED droppers, working out fuse and wire ratings, reading how much a heater or motor will draw, and predicting the heat a resistor must dissipate. It does not by itself describe capacitors, inductors or non-ohmic parts like diodes, where the voltage–current relationship is no longer a straight line.
Takon kang asring diajukake
Apa hukum Ohm?
Hukum Ohm nerangaké yèn arus listrik ing konduktor proporsional karo tegangan listrik ing konduktor: V = I × R. Disusun manèh, I = V / R lan R = V / I.
Apa aku bisa nemokaken daya listrik saka hukum Ohm?
Kajaba iku, kaluwihan saka sistem iki ya iku bisa digawé saka 100% bahan baku lokal, lan bisa digawé kanthi cara sing gampang lan murah.
Dumuginipun ingkang dipunsebat kawula punika ingkang dipunsebat kawula.
Pilih kuantitas kang sampeyan ora weruh ing "Solve for", banjur ketik siji saka telu liyane. Kanggo nemokake resistansi, sampeyan bisa nyedhiyani voltase lan arus, utawa daya lan arus.
Apa kula saged ngginakaken daya kanggé input kanggé ngganti voltase utawi arus?
Ya. Medang daya maju mènèhi sampeyan kamungkinan kanggo nyelesaiké saka daya ditambah siji kuantitas liyane - contoné, 24 W load ing2A bakal bali 12 V lan6Ω, nganggo V = P / I lan R = P / I².
Apa hukum Ohm kerja kanggo sirkuit AC?
Iki langsung ditrapaké ing pérangan resistif saka sirkuit AC. Kanggo sirkuit kanthi kondensor utawa induktor, sampeyan bisa ngganti resistansi karo impedansi, lan daya njupuk faktor daya, nanging resistor biasa ngrembaka V = I × R ing saben wektu.
Apa kang dadi sebabé, apa kang dadi akibaté, apa kang dadi akibaté?
Ing basa Inggris, 100 watt iku 100 watt, lan 1 watt iku 100 watt. 100 watt iku siji unit daya listrik, kang dipérang dadi 100 watt utawa 100 watt = 100 watt.
Apa iki ngontrol pérangan non-linear kaya diode utawa LED?
Ora. Hukum Ohm ngandhakaké resistansi kang konstan, mula ora nggambaraké diodes, LED utawa transistor kang arusé mundhak ora linear karo tegangan. Kanggo LED, sampeyan bisa ukuran resistor seri saka tegangan pasokan daya kurang saka tegangan LED maju.
